“…[72] Spectral assignments, confirmed through 2D-NMR spectra, were in agreement with literature data. [69][70][71] Methyl glycosides were commercial samples. 1,3,5-tris(Aminomethyl)-2,4,6-triethylbenzene 3, 1,3,5-triethyl-2,4,6-tris(bromomethyl)benzene 8, [28] 5-(5,5-Dimethyl-1,3-dioxan-2-yl)-pyrrole-2-carbaldehyde 23 [40] and pyrrole-2,5-dicarbaldehyde 24, [40] 2,3dimethylbutane-2,3-diamine 42 [73] were prepared according to known method.…”
